I have bought a 1999 Lincoln Towncar, its skips & spurts, will not run right. We have checked the EGR Valve it open & closes fine, still has random mis fires. We have replaced Igition Boots,Fuel pump & fuel filter, fuel strainer, switch housing...What else is wrong???Help please.
There is an almost endless list as to what could cause an engine to run rough. To correctly diagnose the problem, I suggest bringing your vehicle to a qualified technician. It may be an easy part that you can replace yourself, but it will save a lot of time and money to correctly diagnose the problem first.
